But what do we know about the imminent arrival? HITC Sport answers five key questions...

5) How much will he cost?

According to the Mail the deal is £1 million, though whether this is an up-front payment or over installments remains to be seen.

4) Where does he play?

Listed as a striker in most places, Calvert-Lewin can operate in a variety of roles, notably centre-forward, number 10 or wide left.

"Dom is great at holding the ball up," said former Blades boss Nigel Clough, as quoted bythe Worksop Guardian.

"He’s a big lad who is good technically for the stage he’s at and he’s going to win headers against anybody. He’s got an incredible spring."

3) How experienced is he?

The 19-year-old has to his name just 31 Football League appearances, all of which were accrued over the past 15 months - and the vast majority (20) during a spell at Northampton Town.

2) Is this not a bit soon?

Though he only started four times for the Blades last season, a summer exodus, combined with the appointment of his former Northampton boss Chris Wilder at Bramall Lane, suggests Calvert-Lewin's first-team chances are set to improve.

Should Everton, who can call on Brendan Galloway and John Stones as evidence of their Football League talent-developing prowess, allow that to happen, the asking price could rocket and others' attentions pique.
